Why is my BSM light on?
The BSM is designed to assist the driver in checking the area to the rear of the vehicle on both sides during lane changes by notifying the driver of the presence of vehicles approaching from the rear in an adjacent lane. The BSM detects vehicles approaching from the rear while traveling in the forward direction at a speed of 10 km/h (6.3 mph) or faster and notifies the driver by turning on the BSM warning indicator light and displaying the vehicle detection screen (vehicles with multi-information display and active driving display).
If the turn signal lever is operated to signal a turn in the direction in which the BSM warning indicator light is illuminated while the approaching vehicle is detected, the BSM notifies the driver of possible danger by turning on the BSM warning indicator light, and by activating the warning sound and the warning screen indicator display (vehicles with multi-information display and active driving display).
The detection area on this system covers the driving lanes on both sides of the vehicle and from the rear part of the front doors to about 50 m (164 ft) behind the vehicle. Always check the surrounding area visually before making an actual lane change: The system is only designed to assist you in checking for vehicles at your rear when making a lane change. Due to certain limitations with the operation of this system, the BSM warning indicator light, the warning sound and the warning screen indicator display may not activate or they might be delayed even though a vehicle is in an adjacent driving lane.
The BSM will operate when all of the following conditions are met:
The ignition is switched ON. The BSM OFF indicator light in the instrument cluster is turned off. The vehicle speed is about 10 km/h (6.3 mph) or faster.
The BSM will not operate under the following circumstances.
The vehicle speed falls below about 10 km/h (6.3 mph) even though the BSM OFF indicator light is turned off. The shift lever (manual transaxle)/selector lever (automatic transaxle) is shifted to reverse (R) and the vehicle is reversing. The turning radius is small (making a sharp turn, turning at intersections).
In the following cases, the BSM OFF indicator light turns on and operation of the system is stopped. If the BSM OFF indicator light remains illuminated, have the vehicle inspected at an Authorized Mazda Dealer as soon as possible.
Some problem with the system including the BSM warning indicator lights is detected. A large deviation in the installation position of a radar sensor (rear) on the vehicle has occurred. There is a large accumulation of snow or ice on the rear bumper near a radar sensor (rear). Remove any snow, ice or mud on the rear bumper. Driving on snow-covered roads for long periods. The temperature near the radar sensors (rear) becomes extremely hot due to driving for long periods on slopes during the summer. The battery voltage has decreased.
Under the following conditions, the radar sensors (rear) cannot detect target objects or it may be difficult to detect them.
A vehicle is in the detection area at the rear in an adjacent driving lane but it does not approach. The BSM determines the condition based on radar detection data. A vehicle is traveling alongside your vehicle at nearly the same speed for an extended period of time. Vehicles approaching in the opposite direction. A vehicle in an adjacent driving lane is attempting to pass your vehicle. A vehicle is in an adjacent lane on a road with extremely wide driving lanes. The detection area of the radar sensors (rear) is set at the road width of expressways.
In the following case, the flashing of the BSM warning indicator light, and the activation of the warning sound and the warning screen indicator display may not occur or they may be delayed.
A vehicle makes a lane change from a driving lane two lanes over to an adjacent lane. Driving on steep slopes. Crossing the summit of a hill or mountain pass. When there is a difference in the height between your driving lane and the adjacent lane. Directly after the BSM system becomes operable by changing the setting.
If the road width is extremely narrow, vehicles two lanes over may be detected. The detection area of the radar sensors (rear) is set according to the road width of expressways. The BSM warning indicator light may turn on and the vehicle detection screen may be displayed in the display in reaction to stationary objects (guardrails, tunnels, sidewalls, and parked vehicles) on the road or the roadside. A BSM warning indicator light may flash or the warning beep may be activated several times when making a turn at a city intersection. Turn off the BSM while pulling a trailer or while an accessory such as a bicycle carrier is installed to the rear of the vehicle.
Snow or ice is adhering to the door mirrors. The front door glass is fogged or covered in snow, frost or dirt.
The radar sensors (rear) of the BSM may be regulated under the radio wave related laws of the country where the vehicle is driven. The sensors in this system are approved for use in the U.S.A. (including territories), Canada, and Mexico. If a vehicle with a BSM is driven in a country other than the U.S.A., Canada, or Mexico, the system has to be turned off by changing the setting on the center display. The system switches to the Rear Cross Traffic Alert (RCTA) function when the shift lever (manual transaxle) or the selector lever (automatic transaxle) is shifted to the reverse (R) position. Refer to Rear Cross Traffic Alert (RCTA) (Search).

Does BSM make noise?
Blind-Sport Warning Just an alert, this BSM system issues a visual warning usually found on the outboard mirror or the A-pillar on the side with the potential danger. More involved versions will also sound an audible warning if you engage the turn signal on that side.
What does BSM mean on battery?
The Battery System Monitor (BSM) integrates wireless battery sensing with your NetGuardian RTU (many NetGuardian models are supported). This creates a single logical device that’s monitoring your equipment alarms, environmental alarms, and battery strings.
Whether you have 2V or 12V cells (or something in between), the BSM gives you complete visibility over battery conductance, voltage, temperature, and intercell connection integrity resistance). Simple wiring harnesses minimize the installation time for attaching the sensor modules to your batteries. Live analog values and threshold alarms can be accessed via SNMP, a T/Mon master station, the NetGuardian’s built-in web interface, or SMS/email alerts.
The BSM is an excellent solution for battery string monitoring in both industrial telco and IT environments.
How do BSM sensors work?
How Does Blind-Spot Monitoring Work? Blind-spot monitoring uses sensors on the outside of the car to keep an eye on your blind spot. If these sensors detect a car in your blind spot where it might not be visible in your mirrors, a little light will turn on to let you know.
What is BSM alarm?
BSM（Blind Spot Monitoring） It alerts drivers to the presence of vehicles in the blind spot on either side by displaying an icon in the appropriate door mirror. If the driver indicates to change lanes with a vehicle in the blind spot, the icon flashes and a warning beep is sounded.
Why is my BSM light on my Toyota Green?
Toyota RAV4 BSM Light on Dashboard – If you don’t know what BSM is, seeing the dashboard light may be confusing. But don’t worry, there’s nothing wrong with your car! A green “BSM” light on your RAV4’s dashboard means your blind spot monitor is turned on. Your blind spot monitor will alert you if a vehicle enters your blind spot. 
If you don’t see the green “BSM” light on the dashboard, there are two possible reasons why:
- The BSM is turned off
- Your vehicle is not equipped with BSM
